How much wool do I need for knitting? Complete guide by project type
Share
One of the most frequently asked questions among those just starting to knit—and also among those who already have experience—is:
How much wool do I need to knit my project?
There is no single answer, but there is a clear formula: it depends on the type of garment , the thickness of the thread , the stitch and the final size .
In this guide, we'll help you easily calculate it and provide you with direct access to our guidance tables based on the type of work.
How to calculate how much wool you need
Before choosing your balls of yarn, it's a good idea to consider four key factors:
1️⃣ The type of project
Each type of garment requires a different amount of yarn. For example, a blanket uses much more yarn than a hat or a pair of socks.
2️⃣ The thickness of the thread
The greater the thickness, the fewer meters you will need , since each point covers more surface.
For example:
- A fine yarn (Fingering or Sport) yields more meters, but requires more stitches.
- A thick wool (Bulky or Super Bulky) knits faster, but consumes more grams.
3️⃣ The point or texture
Some stitches “use” more thread:
- Garter stitch or cables: tighter → more wool.
- Jersey or lace stitch: lighter → less wool.
4️⃣ Tension and size
Your knitting style influences this: if you knit more tightly, you'll use more yarn; if you knit loosely, you'll use less.
That is why it is important to always make a 10 x 10 cm sample to adjust the tension.
